I'm 24, female, previously treated for depression&anxiety. stopped treatment sometime this yr. been experiencing memory loss.what could this be?

Memory is sensitive: Normal human memory is quite sensitive to our responses to life events, our moods, sleep, interference due to past learning, medications, blood sugar levels, etc. Memory also may work better when one experiences significantly more positivity than negativity. Our memories don't work like computers. Rehearsal and deeper processing of information helps.

Depression anxiety: Depression and anxiety can cause problems with memory. There are also certainly physical illnesses such as thyroid disorders, B12 or folate (folic acid) deficiency, and other central nervous system infections etc. That can cause difficulty with memory. I would suspect that yours is due to the stopping of your medication. Please return to your psychiatrist to be restarted on your medications and to be evaluated for any possible underlying physical conditions. Best wishes. Don't forget psychotherapy as well.
